Calculated Fingerprint Identifier. The Fingerprint is assigned by the agency creating a record. Not repeatable.
An identification in coded form of the system from which fingerprint identifier is derived. Not repeatable.
Name of institution to which field applies in coded form. Codes should be entered in accordance with the provisions of International Standard Identifier for Libraries and Related Organizations (ISIL), ISO 15511. (Existing records may contain codes from MARC Code List for Organizations, the full name of the agency or a national code). If the institution holds more than one copy the shelfmark of the item should be added after a colon; however, it is strongly recommended that this be done even if the copy is the only one held at the time of cataloguing. Mandatory. Not repeatable.
Since no definitive formula for fingerprint has been determined by international agreement, various forms of fingerprint will be considered acceptable. It is recommended to use a method of fingerprint construction found in Fingerprints = Empreintes = Impronte. Paris : Institut de Recherche et d'Histoire des Textes in association with the National Library of Scotland, 1984.
The field contains the International Standard Book Number.
The field contains a note on the fingerprint identifier.
EX 2: 012 ##$a165512 - a1 *2 dol : a2 *6 m$ - b1 A r : b2 2E7$quid$$2stcn$5NeHKB
Fingerprint for Erasmus' Colloqvia. Amstelodami, 1655. Fingerprint taken from a copy in the Royal Library (Koninklijke Bibliothek), Den Haag, using the system devised for the Short Title Catalogue (Netherlands). The dollar signs of 'm$' and '$quid$' form part of the fingerprint and are not subfield identifiers.
013 INTERNATIONAL STANDARD MUSIC NUMBER (ISMN)
Field Definition
This field contains an International Standard Music Number and a qualification which distinguishes between ISMNs when more than one is contained in a record. The field corresponds to the ISBD Standard Number (or Alternative) and Terms of Availability Area. The field may contain the terms of availability and/or price, even if it does not contain an ISMN.
Occurrence
Optional. Repeatable when more than one valid ISMN is to be recorded.
Indicators
Indicator 1: blank (not defined)
Indicator 2: blank (not defined)
Subfields
$a Number (ISMN)
A correctly applied ISMN including hyphens. The ISMNs are assigned by the designated agency in each country. Not repeatable.
$b Qualification
An indication of the scope of the ISMN in subfield $a (if present), usually the name of a publisher, an indication of the binding of the item, or an indication of the relationship of an ISMN to a set or to a particular volume (EX 1, 2). Not repeatable.
$d Terms of Availability and/or Price
The price of the item and any comment on its availability. Where there is an 010 International Standard Book Number field and the contents of this subfield would simply repeat what is in 010$d then the subfield can be omitted. Not repeatable.
$z Erroneous ISMN
An ISMN that has been identified as being erroneously applied to an item or is otherwise invalid. It may have been allocated to two different publications and in this instance cancelled, or it may have been incorrectly printed (EX 3). Repeatable.
Notes on Field Contents
ISMN structure:
The ISMN is used to identify music publications, whether available for sale, hire, gratis or for copyright purposes only, according to the provisions of ISO 10957.
Each separately available constituent part of a publication must receive its own ISMN. An ISMN consists of the letter M followed by nine digits. Whenever it is printed or written, the number is preceded by letter ISMN. In countries where the Latin alphabet is not used, an abbreviation in the local script may be used in addition to the Latin letters ISMN.
The ISMN is divided into four elements, two of which are of variable length, each of which is separated by a hyphen or space.
Distinguishing element: The letter M distinguishes the ISMN from the ISBN.
Publisher identifier: Designates the publisher of a given music publication. It is allocated to each publisher by a national or regional ISMN agency.
Item identifier: Identifies an edition of a work and the various items within it. An
item, in the terms of the Standard, is one separately saleable or available or obtainable constituent part of a music publication.
Check character: This is a single digit at the end of the ISMN that provides an automatic verification of the correctness of the ISMN. It is computer calculated.
Verification of check character: The check character is calculated on a modulus 10 with alternating weights of 3 and 1 assigned from left to right beginning with the letter M prefix. The letter M counts as 3.
This means that each of the first nine characters of the ISMN – i.e. excluding the check digit itself – is multiplied by an alternating sequence of the numbers 3 and 1 from left to right and that the sum of the products thus obtained, plus the check digit, must be divisible without remainder by 10.

Total: 65 + 5 (check digit) = 70
As 70 can be divided by 10 without remainder M-345-24680-5 is a valid International Standard Music Number.
Data format:
The letters ISMN, which are usually found printed with an ISMN on the item, should not be entered in field 013.
Any ISMN which is found to be wrongly printed on the item can be entered in subfield $z, Erroneous ISMN, which is provided to give access to records that may have been requested by an erroneous number appearing on the item.
Hyphens are inserted to separate the four parts of the number in the $a or $z subfield. No other punctuation is permitted. The purpose of the hyphens or spaces in the ISMN is to separate the distinct parts. When an ISMN is displayed in a catalogue entry the inclusion of the hyphens or spaces is mandatory. Many national agencies do not store the hyphens or spaces in the machine-readable record since they can be generated by algorithm if the range of publisher identifiers which have been allocated is known. When records are exchanged internationally the recipient of records may not always know the range of publisher identifiers. Therefore it is recommended that hyphens always be included in the ISMN in field 013 to ensure the display output.
Strictly speaking, each music publication has one ISMN. However, there are circumstances in which a single record may need to include more than one ISMN, depending on the policy of the cataloguing agency. Examples of situations in which multiple ISMNs might appear in a record are: where a publisher issues a work in more than one binding or physical format, each with a different ISMN, and a single record is created by the agency encompassing more than one of the 'editions', where a single record is created for a multi-volume publication and different ISMNs have been assigned by the publisher to each individual volume in the set and to the set as a whole; where a single item is published, or published and distributed, by more than one entity, each of which has assigned a separate ISMN to the item.
In order to distinguish between ISMNs when there is more than one in a record, qualifications may be added to one or more of them, according to the practice of the agency preparing the record.
Terms of availability and price are often related to each ISMN. Thus this information is recorded in the same field. Punctuation is included with the data as required.
The field should be repeated for each valid ISMN. It should be repeated for an invalid ISMN unless that invalid ISMN clearly relates to a known valid equivalent entered in the record, in which case the invalid ISMN will be entered in the same field as its corresponding valid ISMN (EX 3).
Some agencies may use the ISMN as record identifier and enter it in the field 001. In those cases the ISMN should be entered additionally in field 013.
